Segmental bridges

Balanced cantilever erection using mobile cranes has frequently been used by VSL Group. When site and ground conditions are suitable, this method has proved highly effective and can facilitate considerable rates of erection. Other advantages include a relatively easy availability of cranes at local market, their possible subsequent utilisation on site, minimum requirements for temporary structures, and optimisation of labour forces.

VSL project teams provide detailed craneage studies helping to optimise crane usage, while minimising disruption to the surrounding environment. VSL technical centres work with production teams to develop additional temporary works, in particular pier segment supports and work platforms. VSL is also capable of offering the structure analysis in all phases of construction, including detailed pre-camber calculation. With careful project design and management, VSL has achieved excellent results of construction. Typical erection cycle is 6 segments per day.
